Comment 2 Myriam Schweingruber 2010-03-07 09:02:06 UTC 
Isn't this a Qt bug, and a duplicate of bug 227639?
Comment 3 Paulo Dias 2010-03-08 19:48:53 UTC 
It might be a duplicate but amarok crashes on startup in bug 227639 most probably because the info applet is already active, remove it and amarok will start.

it might be  a good idea not to ship info applet in 2.3.0 if this bug cant be fixed in amarok, cause thie minute the users activate it and restart amarok they wont be able to start it. very annoying :(
Comment 4 Paulo Dias 2010-03-16 21:36:17 UTC 
still there in 2.3.0 final AND 2.3.1 git from today (btw coberbling is awesome) :), any idea when this will be fixed?

best regards
